"I just have faith in my wallet to not mismanage my crypto": Investigating Changes in Users' Security Perceptions Post-FTX Collapse

Non-custodial wallets (NCWs) grant users full control over their keys and crypto assets, whereas custodial wallets (CWs) rely on centralized exchanges. Security breaches at major exchanges are on the rise, exemplified by the 2022 FTX fraud, yet their influence on users' security perceptions and risk mitigation behavio…

Endless Swipes and Recommendations: The Impact of Short-Form Video Platforms on Context-Switching and Children’s Working Memory

Short-form video (SFV) platforms are increasingly popular, yet the rapid context switching and their potential effects on children’s cognitive functions are not well understood. In this work, we conducted a between-subjects experiment ($N = 180$) to examine how YouTube Shorts affects young children’s short-term memory…

Understanding and Improving User Adoption and Security Awareness in Password Checkup Services

Password checkup services (PCS) identify compromised, reused, or weak passwords, helping users secure at-risk accounts. However, adoption rates are low. We investigated factors influencing PCS use and password change challenges via an online survey (n=238). Key adoption factors were "perceived usefulness," "ease of us…

BallistoBud: Heart Rate Variability Monitoring using Earbud Accelerometry for Stress Assessment

This paper examines the potential of commercial earbuds for detecting physiological biomarkers like heart rate (HR) and heart rate variability (HRV) for stress assessment. Using accelerometer (IMU) and photoplethysmography (PPG) data from earbuds, we compared these estimates with reference electrocardiogram (ECG) data…

ID.EARS: One-Ear EEG Device with Biosignal Noise for Real-Time Gesture Recognition and Various Interactions

In-ear EEG research has traditionally treated biological signals other than brainwaves, such as electromyography (EMG) and electrooculography (EOG), as unwanted noise to be removed. However, instead of discarding these signals, we developed ID.EARS, a single-ear, dry electrode-based device that utilizes these signals…

Characterizing and Quantifying Expert Input Behavior in League of Legends

To achieve high performance in esports, players must be able to effectively and efficiently control input devices such as a computer mouse and keyboard (i.e., input skills). Characterizing and quantifying a player’s input skills can provide useful insights, but collecting and analyzing sufficient amounts of data in ec…

SkullID: Through-Skull Sound Conduction based Authentication for Smartglasses

This paper investigates the use of through-skull sound conduction to authenticate smartglass users. We mount a surface transducer on the right mastoid process to play cue signals and capture skull-transformed audio responses through contact microphones on various skull locations. We use the resultant bio-acoustic info…

On the Long-Term Effects of Continuous Keystroke Authentication: Keeping User Frustration Low through Behavior Adaptation

"One of the main challenges in deploying a keystroke dynamics-based continuous authentication scheme on smartphones is ensuring low error rates over time. Unstable false rejection rates (FRRs) would lead to frequent phone locks during long-term use, and deteriorating attack detection rates would jeopardize its securit…

WristAcoustic: Through-Wrist Acoustic Response Based Authentication for Smartwatches

PIN and pattern lock are difficult to accurately enter on small watch screens, and are vulnerable against guessing attacks. To address these problems, this paper proposes a novel implicit biometric scheme based on through-wrist acoustic responses. A cue signal is played on a surface transducer mounted on the dorsal wr…

Exploring Digital Communication Needs of Local Communities and Self-organized Collectives

Recent work in HCI has explored the use of ICTs for the mobilisation and organisation of values-led communities and social movements. This paper extends this line of work by exploring the design of a communication system for informal, place-based citizen collectives—also referred to as Social Solidarity Movements. The…
